With the very similar layout as the original, the MBX3 has one oscillator with sawtooth or pulse waveform and a sub oscillator with sine waveform, followed by an analog-modelled 24db lowpass filter with modified resonance reaction and passive-controlled overdrive circuit inside the filter. Like the original the MBX3 has a distortion fx unit on the signal output for more aggressive sound shaping. All the features united with 2x oversampling and low cpu demand.
